Knox City, MO population, income and ZIP codes

Knox City city is a very small community in Missouri, with 143 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #809 of 1,082 ranked by population — larger than 25% of them. The median age here is 51.2 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Knox City city earn a median of $43,500 a year, 44.6% below the national figure of $78,538 and 22% below the $55,543 median for the 374 Missouri cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 0.7% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Knox City city is valued at $57,500, 81% below the national figure and 62% below the $152,400 peer median, while median gross rent runs $725 a month, 48.4% below the national figure, or roughly $8,700 across a full year. A household on the local median income would put about 20% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 1.3×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 85.4% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

A median age of 51.2 puts Knox City city well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 143 residents, a handful of survey responses moves every median on this page. Compare Knox City city against its county rather than against national figures.

All values below were released by the Census for this exact geography, with no gap-filling on our side. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
